Curtain membrane module is mainly used for membrane bioreactor(MBR). Membrane material, basing on PVDF with good resistance to oxidation, is generally divided into normal type and enhanced type. The normal type curtain membrane module is normally used in the good feed water condition, like municipal water. The enhanced type curtain membrane module featuring in high tensile strength is normally used in bad feed water condition which needs chemical wash or aeration process.
